Hemodynamic Strategy 2026–2027 | Practice Questions,
Rationales & Exam Study Guide
Course Code: NURS 4420
Course Name: Advanced Cardiovascular Critical Care Nursing
Topic: Acute Coronary Syndromes, Hemodynamic Crisis Management, and
Mechanical Circulatory Assist Devices
Academic Year: 2026/2027
Question 1
A 58-year-old female presents to the emergency department with acute-onset
epigastric distress, severe upper back pain, and a sudden syncopal episode.
The initial 12-lead EKG reveals ST-segment depression and prominent T-wave
inversion in leads V1 through V4. Given this patient's clinical presentation,
which sequence represents the highest priority diagnostic and pharmacological
intervention to prevent myocardial death?
A. Obtain an immediate chest X-ray, administer oral acetaminophen, and schedule
an outpatient stress test.
B. Obtain immediate serum troponin biomarkers, initiate sublingual
Nitroglycerin with continuous core vital monitoring, and administer chewed
non-enteric Aspirin.
C. Prepare for an emergency open-heart Coronary Artery Bypass Graft (CABG)
surgery before checking lead placement.
D. Administer high-dose continuous intravenous loops of Lasix and restrict all
supplemental oxygen delivery.
CORRECT ANSWER: B
RATIONALE: This patient is presenting with a Non-ST-Elevation
Myocardial Infarction (NSTEMI). Women frequently present atypically with
indigestion, fainting, upper back, or lower abdominal pain rather than classic
crushing substernal chest pain. Because her EKG shows ST-segment depression
and T-wave inversion, the diagnosis must be confirmed by measuring elevated
serum troponin biomarkers. Emergency management dictates the immediate
implementation of the "ONAM" framework. The most critical initial goal during
,an acute coronary occlusion is to ensure the clot does not get bigger, which is
achieved by administering antiplatelets like chewed Aspirin. Nitroglycerin is
administered simultaneously to dilate coronary arteries, increase blood flow,
and decrease myocardial oxygen demand. A stress test is strictly contraindicated
during active ischemic pain and is performed only after the patient has been fully
stabilized.
Question 2
A patient with an extensive history of chronic atherosclerosis is admitted to the
cardiac care unit following an emergency percutaneous coronary intervention
(PCI) with a single stent. The nurse practitioner is formulating the post-operative
medication regimen and discharge education blueprint. Which combination
represents the mandatory dual-therapy pharmacological standard for this patient?
A. An H2 receptor antagonist mixed with high-dose systemic oral corticosteroids
B. A dual regimen consisting of an antiplatelet agent (e.g., Clopidogrel) and an
anticoagulant (e.g., Heparin or Warfarin)
C. Absolute restriction of fluid intake combined with a continuous subacute loop
diuretic
D. An oral potassium supplement paired with a short-acting nitrate used every 5
minutes
CORRECT ANSWER: B
RATIONALE: Following a stent placement via cardiac catheterization, the
newly deployed intraluminal foreign body is highly thrombogenic. To prevent
acute stent thrombosis and re-occlusion, current critical care guidelines dictate that
the patient must be discharged home on a combined regimen of an antiplatelet
and an anticoagulant. Specifically, antiplatelets like Clopidogrel or Aspirin
inhibit platelet aggregation along the arterial mesh wall, while anticoagulants or
specialized bridges alter the coagulation cascade. Combining these mechanisms is
the gold standard for maintaining vessel patency post-PCI. Systemic
corticosteroids or fluid restrictions play no role in routine post-stent management
and can increase structural complications.
Question 3
,An advanced critical care nurse is managing a patient who has just returned to the
unit following a Coronary Artery Bypass Graft (CABG) multi-vessel open-
heart surgery under general anesthesia. Which of the following sets contains the
most critical post-operative trending parameters and nursing interventions
that must be executed and documented every 15 minutes?
A. Measuring long bone length, checking color vision limits, and calculating body
mass index
B. Trending blood pressure and heart rate, titrating vasoactive medications,
monitoring chest tubes for blood accumulation, and evaluating electrolyte and
sedation levels.
C. Mandating continuous rapid ambulation, administering high-dose oral
antipyretics, and clamping all chest tubes permanently
D. Restricting all intravenous access lines and switching the patient to an entirely
solid oral diet immediately
CORRECT ANSWER: B
RATIONALE: Post-operative care for a patient undergoing a CABG open-
heart surgery requires highly meticulous, rapid surveillance in an intensive care
setting. The nurse must trend blood pressure and heart rate every 15 minutes,
titrating continuous vasoactive infusions to maintain optimal systemic perfusion
without straining the new vascular grafts. Additionally, monitoring chest tubes
for blood accumulation is critical to ensure blood does not build up in the
thoracic cavity, which could lead to a fatal cardiac tamponade. Managing the
mechanical ventilator, checking electrolytes (especially Potassium to prevent
PVCs), and maintaining a safe level of sedation and pain management are
fundamental priorities during this immediate recovery window.
Question 4
A patient with end-stage heart failure who is not a candidate for a cardiac
transplant is being evaluated for a Left Ventricular Assist Device (LVAD). When
discussing treatment options with the family, how should the nurse explain the
clinical significance of LVAD Destination Therapy?
A. It functions as a temporary 24-hour external bridge used until an immediate
donor heart becomes available.
B. It serves as a long-term permanent mechanical assist option for patients
who are not transplant candidates, aimed at improving their overall quality of
, life.
C. It is a short-acting over-the-counter automated medication patch applied directly
to the thoracic wall.
D. It completely eliminates the need for the patient to remain within a specific
geographic distance from a hospital.
CORRECT ANSWER: B
RATIONALE: An LVAD is a surgically implanted mechanical pump that
connects to the left ventricle and the aorta to support systemic blood flow and
allow an injured or failing heart to rest. In clinical practice, LVAD therapy is
governed by two distinct logistical goals. Bridge therapy involves implanting the
device as a temporary support mechanism while the patient waits on an active
registry for a heart transplant. In contrast, Destination Therapy is utilized when
the patient is not a candidate for a transplant; it serves as a long-term,
permanent support option designed to improve the patient's quality of life and
keep them comfortable for their remaining time. A critical requirement for any
LVAD patient is the strict safety mandate that they must remain within a 20-mile
geographic radius of the hospital to ensure immediate access to specialized care
during a mechanical crisis.
Question 5
A patient with a history of chronic hypertension is admitted in an acute state of
confusion, complaining of a blinding headache and visual disturbances. The vital
signs reveal a blood pressure of 210/130 mmHg with clear evidence of acute target
organ dysfunction. The nurse practitioner recognizes this as a Hypertensive
Emergency and prepares to implement which immediate protocol?
A. Administer a single dose of an oral beta-blocker and allow the patient to
ambulate freely for 48 hours.
B. Initiate continuous intravenous vasodilators (such as Sodium Nitroprusside
or Nitroglycerin) to lower the blood pressure safely by 20% to 25% within the
first hour.
C. Place the patient in a prone position, restrict all oxygen access, and perform a
rapid fluid bolus of normal saline.
D. Schedule a routine outpatient screening transesophageal echocardiogram (TEE)
to be completed over the next week.
